If an = n(an-1) and a1 = 1, what is the value of as?
1) 5
2) 20
3)
120
4) 720
Answers
The value of a5 is a5=120.
Here, we have,
given that,
an = n(an-1) and a1 = 1,
now, we have,
a1 = 1
so, we get,
a2 = 2(a1)
= 2
and, a3 = 3(a2) = 6
a4 = 4(a3) = 24
so, we get,
a5 = 5(a4) = 120
Hence, the value of a5 is a5=120.

Answer:
I think it is 72%
Step-by-step explanation:
Answer:
A. 12%
Step-by-step explanation:
I counted the number of dots in all, and the number of dots in the columns 7 - 8.
There are 25 dots in allThere are 3 dots in columns 7 - 8.This means that 3/25 of the students in the class have 7 - 8 people in their houses.
Now let's convert the fraction into a decimal, which we'll then convert into a percent.
Let's multiply the numerator and denominator of 3/25 by 4.
We get 12/100!
12/100 as a decimal is 0.12
0.12 as a percent is 12%
Is there a letter which has 12% as an option? Yes, there is! It's A.
The answer is A. 12%
